Hello all,
I have created an Android app that uses FFmpegKit for streaming video from camera. while streaming,camera power off but FFmpegKit not return any event callback (CompleteCallback, LogCallback, StatisticsCallback not return data).
I check SessionState it always return Running.
So, please help me how to receive callback while streaming,input source (camera) power off .
This is command which i am using:
-i rtsp://CameraStream -c copy -f flv rtmp://xxx/MyStream
Thank you
